The opportunity came because the whole industry was moribund, they couldn't see the wood for the trees. Most of us hated our phones.
They thought the iPhone was just a phone, and judged it in those terms. A massive mistake that allowed Apple to walk away with over 90% of the profits of the entire industry right under their noses. Their network effect advantages didn't help them, because they were obsolete. It's like hoping the network of stables, fields, saddle makers and horseshoe manufacturers will save the horse drawn carriage from the car. The network effects that matter to smartphones are app stores, app developers and services for apps.
The iPhone vision of a hand held computer that happened to make phone calls was way broader than I could get my head around at the time. I remember predicting that there were maybe 10 apps that would ever make money on such a device :-).
Of course my phone does much more now, calling and texting being the least of it. I wouldn't go back ( * ), but I also won't go back to the cars of the 70s. This doesn't mean I hated my dad's car.
Apple invented a new phone which is not a phone as intended before 2007 and one that people liked. That's why they got so successful.
HP and Xerox are probably still good at what they used to do (I'm happy with my ZBook and LaserJet) but they are probably not where the bulk of the market is nowadays. So they seem to be fading away.
(*) Except that phones got so light and small around 2000 that they could almost fit in a closed fist and I'm missing that.
I somehow hate smartphones nowadays because of the "more is less" dimension but the iphone was a normal thing to happen.
When a technology is at the point where it is maturing, the cost of entry is bank-breaking. By then the first movers have attracted serious capital, but more importantly they have network effects on their side. Everyone can see this is the way to go and they are way ahead of you. There’s a decision point, spend billions to probably be an also-ran anyway, or essentially give the money to the shareholders.
Everybody focuses on the technology, but it’s the network effects that really matter. This is why WebOS and Windows Phone failed, why couldn’t HP and Microsoft buy their way into the mobile phone landscape? Their technology was excellent. The problem was the weren’t competing with Apple and a Google. They were competing with them, plus all the companies that had invested in the iPhone and Android ecosystems. The carriers, device manufacturers, software developers, service companies, all with huge investments in those platforms. Add that all up and it’s maybe 10x as much as just Apple and Google on their own. By now, probably a lot more.
So it’s all about timing. Google knew this, which is why 20% time happened. You pretty much have to invent the future to have any chance of owning it, or even getting a slice. Google was just incredibly lucky that Android fell into their laps at just the right time, and was powerful enough to compete with iOS. So the problem is, how do you keep genuinely innovating?
